I am the mega evil Empire and I shall rule the universe!
Sorry
Seriously though being the mega evil Empire has it's advantages, it makes getting rid of those pesky guys you never wanted to ally with in the first place, much easier. It also adds a "seige" like element which is IMHO LOTS of fun, barely scrounging up enough ships to fight off the raids for just one more month, sacrificing one world to save another more valuable one, oooooh I love it
